Question

a chicken with black feathers (bb) is crossed with a chicken with white feathers (ww). the offspring have black and white feathers. what is the genotype of the offspring? 1. 2. 3. 4. done

Explanation:

Step1: Determine the gametes

The black - feathered chicken (BB) can only produce gametes with the allele \(B\). The white - feathered chicken (WW) can only produce gametes with the allele \(W\).

Step2: Fill in the Punnett square

When we cross \(BB\times WW\), in the Punnett square:

• Square 1: \(B\times W = BW\)
• Square 2: \(B\times W = BW\)
• Square 3: \(B\times W = BW\)
• Square 4: \(B\times W = BW\)

Answer:

The genotype of the offspring is \(BW\) for all four squares (1, 2, 3, 4) in the Punnett square.
